Soil Water Potential Sensors
Heat dissipation and electrical resistance
229-L Water Matric Potential Sensor
The 229 is a probe that measures soil water potential from 0.1 to 10 bars. It requires connection to either the CE4 or CE8 current...
227-L Soil Matric Potential Block
The 227 is a cylindrical gypsum block that estimates soil water potential from 0.1 to 10 bars. It connects directly to a datalogger.
223-L Soil Matric Potential Block
The 223 is a cylindrical gypsum block that estimates soil water potential from 0.1 to 10 bars. It connects to a datalogger via an AM16/32-series...
253-L Soil Matric Potential Block
The 253 is a solid-state, electrical-resistance sensing device with a granular matrix that estimates soil water potential from 0 to -2 bars (typically, wetter or...
257-L Soil Matric Potential Block
The 257 is a cylindrical gypsum block that estimates soil water potential from 0 to -2 bars (typically, wetter or irrigated soils). It connects directly...
